The Atmosphere

Atmosphere - A blanket of air that surrounds the Earth.

What do you think air is made of? Air is made up of gases: • 78% nitrogen • 21% oxygen • 1% trace gases (a combination of several gases)

Fun Fact About Oxygen We require oxygen to breathe but we breathe air that is made up of only 21% oxygen. Would air that is 100% oxygen be better for us? Actually 100% oxygen can be harmful. It can cause nausea, dizziness and chest pains.

How Earth’s Atmosphere Compares to our neighbors

The atmosphere is divided into four distinct layers. 1. 2. 3. 4. Troposphere Stratosphere Mesosphere Thermosphere • The upper layer of the atmosphere, the exosphere, is the layer beyond thermosphere that includes space.

Troposphere Height: Extends to 0 -10 KM Contains: • People • Weather • Buildings • Bad Ozone Temperature: 18*C— 60*C COLOR RED

Stratosphere Height: Extends from 10 -50 Km Contains: • Flying Planes • Weather Balloons • Good Ozone Temperature: -60*C-0*C Color Yellow

Mesosphere Height: Extends from 50 -80 km Contains: • Meteors Coldest Layer Temperature: 0*C— 90*C Color Green

Thermosphere Height: Extends from 80 -120 km Contains: • Auroras (Northern Lights) • Space Shuttle Orbits Hottest Layer Temp: -90*C Color BLUE

Exosphere Height: Extends from about 400 miles and up. Color Black
